3 Claims. 1

"The invention relates to dishes or food receptacles more particularlydesigned for use in the serving of young children, and fit is the objectof the invention to obtain a construction of dish which when placed upona table or other support will be retained "thereto against displacementby the child.

To this end the invention consists in the construction as hereinafterset forth.

In the drawings:

Fig. 1 is a plan view of the dish;

Fig.2 is aside elevation thereof;

Fig. 3 is a vertical cross section on line 13-3, Fig. l partly inelevation;

Fig. 4 is an elevation of the vacuum cup detached from the plate;

Fig. 5 is a cross section on line 5--5, Fig. 4; and

Fig. 6 is a view similar to Fig. :3 showing the unsupported dish andvacuum cup.

For .the serving of food to young children, it is desirable to hold thedish from displacement by the child. At the same time it is advantageousto have a construction which can be placed in any desired position on atable or other support to be temporarily retained in such position butcapable of being easily removed when necessary.

My invention accomplishes such purpose by an adherent dish of thefollowing construction. A is the dish or food receptacle which may beformed with either a single or a plurality of compartments. At theperiphery of this dish and preferably integral therewith is a flange Bshown as of return bend cross section and which extends downward belowthe bottom C of the dish. Beneath the bottom 0 and enclosed within theflange B is a suction cup D formed of resilient material such as rubber.This cup is centrally apertured to receive a lug E depending from thebottom of the dish to hold the cup concentric therewith. In normalposition the height of the cup is greater than the vertical dimensionbetween the bottom C and the plane of the lower end of the flange B.Thus when the dish is placed on a table or other supporting plane and ispressed downward to contact the flange B with said plane, the suctioncup will be evacuated and, therefore, when released will adhere to saidsupporting plane. To hold the dish to the suction cup, the latter ispreferably duplex having in addition to the downturned cup portion D anupturned cup portion D These may be either separate from each other orpreferably as shown have their chambers connected by the channel D andto the supporting plane.

the dish will only increase the force of adhesion so that :it will beadifiicult or impossible for the which forms the socket for receivingthe lug E. This lug, as shown, has grooves E in its periphery tomaintain constant air connection between the two cups.

With the construction thus far described the vacuum cup D will befrictionally held on the lug E and thereby retained "by the dish. Afterthe food is placed in the dish the latter may be carried to the :table.or to the tray of a high chair. and by then pressing downward both cupportions will be vertically collapsed until the flange B rests upon thesupporting plane. Upon release of the downward pressure the resiliencyof the walls of the cups will elongate "the same vertically to causeadhesion both to the bottom of the dish Any effort to lift child toremove the plate from the position in which it is placed.

' .In order that the plate may be easiiy removed when it is desired todo so, I preferably provide the lower cup portion D with a radialextension D :constituting a handle. This when lifted will raise theportion of the cup D immediately adjacent thereto, which will break theseal permitting air to fill the chambers of both cups and thus oppositeside from the child to be out of his sight and thus prevent tamperingwith the handle. It ;is therefore apparent that while the dish will be'non-displaceable by the child it can be easily removed by theattendant. Also the cup D may be easily removed from the lug E when ther dish is to be washed, the grooves E assisting in breaking the vacuum.

To insure that the handle D of the cup is always placed opposite theopening B in the flange A, the lug E is preferably of a cross sectionwhich can be placed in only one position within the central recess ofthe cup as, for instance, indicated in dotted lines in Fig. 1 of thedrawing. Thus there is one portion E which projects slightly beyond theperiphery of other portions to engage a corresponding channel in therecess and to hold the cup against rotation with the handle D oppositethe opening B.

The dish A is preferably formed with tapering having an opening in oneside thereof, and a suction cup having upwardly and downwardly facingcup portions and a central recess, said cup being beneath said bottomportion and biased to extend below said peripheral flange with said lugfrictionally engaging said recess and being adapted when placed on asupporting surface to evacuate both cup portions by a downward pressureon said dish to contact said peripheral flange with said surface and tothereafter adhere both to said bottom and said surface, said cup beingconcealed by said flange and having a vacuum breaking handle projectingfrom one of the cup portions thereof accessible through the opening insaid flange.

2. A dish having a bottom portion With a centrally depending lug, and aperipheral flange extending below the lower surface of said bottomportion upon opposite sides thereof, said flange having an opening inone side thereof, and a suction cup having upwardly and downwardlyfacing cup portions and a central recess, said cup being beneath saidbottom portion and biased to extend below said peripheral flange withsaid lug frictionally engaging said recess and nonrotatively positionedtherein, said cup being adapted when placed on a supporting surface toevacuate both cup portions by a downward pressure on said dish tocontact said peripheral flange with said surface and to thereafteradhere both to said bottom and to said surface, said cup having a vacuumbreaking handle projecting from one of the cup portions thereof which isheld in registration with the opening in said flange by the non-rotativeengagement of said lug with said central recess.

3. A dish having a bottom portion with a centrally depending lug, and aperipheral portion extending below the lower surface of said bottomportion upon opposite sides thereof, and a suction cup having upwardlyand downwardly facing cup portions and a central recess, said cup beingbeneath said bottom portion and biased to extend below said peripheralportion with said lug frictionally engaging said recess and nonrotatively positioned therein and being adapted when placed on asupporting surface to evacuate both cup portions by a downward pressureon said dish to contact the peripheral portion with said surface and tothereafter adhere both to said bottom and to said supporting surface,said lug and central recess being relatively fashioned to form whenengaged an unobstructed channel therebetween for the free passage of airbetween said cup portions.
